tuned anywhere from 30-34hz sounds great for the R's.

Your building a box for someone but have to ask about tuning. This sounds like fail to me.

You don't have enough room for ported.

called alpine, tuned at 35 hz at 3.8 cubes was highly recommended. failure rate is very high and likely, i expect it. said and done, it plays very accurate, holds a good low note. personally i hate alpine woofers.
